<p>[QUOTE=&quot;desertgem, post: 1403373, member: 15199&quot;]Albertsp, here is a pdf download of the information on this handheld ( which seems to be the one in the photo above).</p><p><a href="http://www.skyrayinstrument.com/PDF/EDX-Pocket-III_Brochure.pdf" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.skyrayinstrument.com/PDF/EDX-Pocket-III_Brochure.pdf" rel="nofollow">http://www.skyrayinstrument.com/PDF/EDX-Pocket-III_Brochure.pdf</a> </p><p><br /></p><p>The largest problem, besides the cost of the instrument and consumables, will probably be incidental such as software upgrades, maintenance, etc. As it is non-destructive, it is limited to surface analysis ( The company offers a different machine to measure plating thickness, etc, but it would have to be destructive to do so. Plated coins and objects would probably test good on the surface, but would do great on non-plated objects. The instrument gives a histogram and this is run through the software for a determination of chemical element and %. ( they show several in the pdf). </p><p><br /></p><p>I would love to have use of one for gemstones as my use of a local FTIR spectrometer is suspect at times, and since college students sometime use it, it is off calibration.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
